And after Sunday's WWHL, we now know why. "I mean he was just unfortunately bit by a dog. He's an animal lover. Like I could see him being a vet at some point that's how much he loves dogs, cats. I can't. I'm not able to discuss it. I've been advised not to at this point."

The good news is that Kash is now "doing awesome." Andy Cohen did confirm that the injury "was potentially serious with his eyes," with Kim adding, "He's doing great. He actually has perfect vision in both eyes which is all we care about. The rest we can fix."

Kash is doing so much better these days that he's even been hitting the batting cages with his family. "First time ever holding a bat for @kroyjaggerbiermann who is 5 and @kashbiermann who is 4," Kim shared over the weekend.
